SEPARABLE SYRINGE.

Application filed May 12, 1925, Serial No. 29,706, and in Germany May 24, 1924.

This invention relates to a separable medical injection syringe wherein a separate pressure handle on the cylinder and a nut screw upon the nozzle of the syringe is em- I ployed for locking the nozzle to the cylinder, and the object of the invention is to so arrange said handle on the nozzle that the handle can be locked to the cylinder simultaneously with the nozzle by means of said nut.

The above and other objects will appear more clearly from the following detail description, when taken in connection with the accompanying drawing, which illustrates a la preferred embodiment of the inventive idea.

The drawing illustrates in longitudinal section the syringe constructed in accordance with the invention.

As shown in the drawing, the nut b is directly screwed upon the nozzle of the syringe, the packing a in the cylinder a on said nozzle being so contracted that said cylinder is locked with the nozzle.

According to the invention the handle a is provided With an opening in its front end for receiving the nozzle 00 and said front end of the handle is interposed between the nut b and the adjacent end of the cylinder 2, so that the handle can be locked by the nut tov the cylinder simultaneously with the nozzle. Owing to its resiliency the handle also protects the cylinder against undue pressure.

WVhat is claimed is:

A separable medical syringe including a cylinder, a nozzle therefor, a nut screwed upon the nozzle of the syringe for looking said nozzle to the cylinder, and a separable handle through the front end of which said nozzle is extended with said front end interposed between the adjacent end of the cylinder and said nut whereby the handle can be locked in position simultaneously with the locking of the nozzle to the cylinder, said handle being resilient to protect the cylinder against undue pressure.

In testimony whereof I have affixed my signature.

DR. OTTO HASSELMANN.
